The transfer sheet comprises a sheet substrate and a porous resin-containing coated layer formed on at least one surface of the substrate. The coated layer has a surface average pore diameter of 0.5 to 50 mu m, having a surface pore opening area ratio of at 10 to 70%, and having a density of 0.1 to 0.8 g/cm<3>. The transfer sheet eliminates disturbance of mottles and dots in the image portion and provides a high quality picture image small in gloss contrast between the blank portion and the image portion.
